The Spamusement forums have the unique honor of having displayed what is probably the most depressing banner advertisement I have ever seen. I'll post a pic when I can, but for now a description will have to do.
It was a poll, and the text was something like
"Who is the Best Roll Model Ever?"
The choices were "Britney Spears", "Lindsay Lohan", and "Paris Hilton".

I so desperately wish that I were making this up. *shoots self in head*

My theory on that one was that it was made so no self-respecting parent (or similar) would respond with anything but a write-in.

And yes, I was going to try to post that one after I posted the first one, but it's difficult to add SWFs to a post. Difficult in the sense of how eating an entire mountain range while neither living nor Vin Diesel is difficult.
